SECOP Compressors – R404A and R134A

Built for Aussie refrigeration pros, these SECOP hermetic compressors cover LBP/MBA duties across R404A and R134a systems from 1/3HP to 1.5HP. They’re a bloody good choice for cold rooms, display fridges, deep freezers and food service gear where uptime matters.

Designed for 220–240V installs, SECOP (formerly Danfoss Compressors) delivers the durability and efficiency tradies expect. Fit it once, and she’ll be right.

Key Features & Trade Benefits

• LBP/MBP line-up (1/3–1.5HP) — match the duty to the job for fewer callbacks and tighter pull-down times.
• Refrigerants: R404A & R134a — proven gases across commercial fridges, freezers and merchandisers.
• 220–240V single-phase — drop-in for Australian power; no messy workarounds.
• Hermetic, compact footprint — easier swaps in tight cabinets and truck bodies, faster changeovers.
• Trade-ready build — robust internals for long service life in hot plant rooms and roof decks.
• Wide model coverage — from SECOP M/T R134a 1/3HP to SECOP L/T R404A 1.5HP, there’s a model for every cold-chain task.

Why This Compressor Matters

Real story: Friday arvo in Brisbane, 36 °C on the roof, bottle cooler running warm at a café. Swapped in a SECOP M/T R404A 1HP, evacuated properly, weighed the charge, and the cabinet was back at setpoint before the tradie finished his iced coffee. Fair dinkum—that’s the reliability you want when the heat’s on.

Pro Tip

On LBP freezers, confirm cap tube/orifice match and evacuate to <500 microns with a micron gauge before charging. It’s the fastest way to avoid moisture-related callbacks. If the cabinet sits in a cold plantroom, consider a crankcase heater for smoother starts.

Compatibility & System Info

• Applications: Cold rooms, upright fridges, merchandisers, chest freezers, under-counter units.
• Refrigerants: R404A (L/T & M/T), R134a (M/T).
• Electrical: 220–240V, single-phase.
• Back-Pressure Ranges: LBP (low temp) & MBP (medium temp).

Local note: For Sydney summers and Perth warehouse installs where ambient temps spike, ensure condenser airflow is A-grade and verify superheat after pull-down—too easy.

FAQs

Q: How do I pick between LBP and MBP?
A: Freezers and deep-freeze = LBP. Fridges, merchandisers, chillers = MBP. When in doubt, match the original spec or message us via Contact.

Q: Will this run on 220–240V single-phase?
A: Yes. This range is designed for AU mains (check model plate for current draw and start gear requirements).

Q: Do I need extra start components?
A: Some systems benefit from a start assist if supply is marginal or line lengths are long. If you need one, see the Related Products below.

Q: Can I use this with R32?
A: This listing is for R404A/R134a models. For flammable A2L/A3 gases, follow Australian licensing and safety guidance. See the official refrigerants overview under Authoritative Link below.
